General Motors is slashing up to 15 percent of salaried jobs and closing as many as five North American plants in the next few years.

General Motors said Monday that it will significantly cut salaried jobs nationwide by up to 15 percent, and could close as many as five plants in North America and two more elsewhere as it plans to discontinue many car models.

According to Automotive News, the global giant plans to cut back several car models in an overhaul of global operations in 2019, similar to the move Ford caught flak for earlier this year. According to a GM spokesperson, the Oshawa Assembly in Canada, Lordstown Assembly in Ohio, and Detroit-Hamtramck Assembly in Michigan will all end production in 2019 and not be allocated any products. Two propulsion plants in Maryland and Michigan will also be cut off.

This doesn’t necessarily mean the plants will close but does put nearly 6,700 employees across the U.S. and Canada at risk, with UAW union contract negotiations coming next year. The models produced at the three plants include the Buick LaCrosse, Cadillac CT6 and XTS, and Chevrolet Impala, Cruze, and Volt.

From the closures, GM expects nearly $6 billion in cash savings by 2020, but the company is facing criticism for not planning to make up the production elsewhere, be it Mexico, China, or another global location. Numerous union representatives have called the move “a slap in the face,” and Canadian Prime Minister Justin Trudeau said on Twitter that he had spoken with Barra and was deeply disappointed in the decision.

In terms of workforce reduction, GM also plans to cut 15 percent of its 54,000 salaried employees, and even slashing global executive positions by 25 percent. That adds up to more than 8,000 jobs, after nearly 18,000 salaried employees were offered buyout packages last week.

According to CEO Mary Barra, the cuts are not a result of any specific foreseen troubles or the recent sales slump the company has been under, but rather an attempt to keep the company “lean and agile.”
